The process which is NOT part of the sedimentary rock formation is:

Correct option is B

Explanation:
Sedimentary rock formation involves a sequence of surface processes:
1. Erosion – breakdown and removal of rocks into sediments
2. Deposition – sediments settle out of water or air
3. Lithification – sediments are compacted and cemented into rock
Intrusion, on the other hand, is a geological process associated with igneous rocks, where molten magma pushes into pre-existing rock layers and cools underground. It has no role in the formation of sedimentary rocks.
Information Booster:
· Sedimentary rocks are formed from particles (sediments) derived from pre-existing rocks or biological materials.
· Common examples: sandstone, shale, limestone.
· Intrusive igneous rocks, like granite, are formed when magma solidifies beneath the Earth’s surface.
Additional Information:
· (a) Deposition – Correct process; sediments settle in basins.
· (c) Lithification – Correct process; conversion of loose sediments into rock.
· (d) Erosion – Correct process; essential for sediment supply.
